The sanitation and cleanliness of food production lines is an important issue involving the health of consumers. Food production should not contain poisonous or harmful substances or factors that may damage or threaten human health. These factors may cause consumers to be acutely or chronically poisoned or infected with diseases, and cause hidden dangers that endanger the health of consumers and their offspring.

The food production line plays an important role in the processing and transportation production process of the food industry. It has the characteristics of simple structure, convenient maintenance, strong versatility, and low cost. It is widely used in machinery and equipment in the food, pharmaceutical, and dairy industries.
With the continuous update and development of production technology in our country, food industry manufacturers generally use food production lines to carry out production operations in order to save production time and improve production efficiency.
01
food sanitation
For the food industry, the meaning of the word hygiene is to create and maintain a hygienic and healthy production environment. Hygiene is an applied science. In order to provide wholesome food, food must be processed by healthy food workers in a clean environment to prevent foodborne illness caused by microbial contamination of food. At the same time, the reproduction of microorganisms that cause food spoilage is minimized. Effective hygiene refers to the process that can achieve the above goals. It includes principles of how to maintain, restore or improve hygienic practices and hygienic environments.

Hygienic requirements for food factories mean that in the whole process of “raw materials-processing-finished products-packaging-storage-marketing”, materials are kept in a safe, hygienic and non-polluted environment from beginning to end. The cleaning and maintenance of the food production line plays an important role in guaranteeing the safe production of food. In the design of food factories, the environment, production equipment, processing technology and process, inspection equipment, storage and transportation requirements and other conditions must be strictly implemented in accordance with food laws and regulations.

existing problems
During the production process of food processing enterprises, it is very important to thoroughly clean the food production line. The production line will produce some deposits after use. If it is not cleaned thoroughly in time, it will directly affect the quality of the product. After the equipment is cleaned, the absolute number of microorganisms can be reduced, and the microbial nutrient sources mainly protein and carbohydrates are washed away, so as to prevent the reproduction of microorganisms. Therefore, maintaining a clean environment on the production line and preventing secondary contamination of microorganisms is also the most effective way to prevent accidents such as food poisoning. In different food production processes, appropriate cleaning conditions should be selected according to the type, nature and cleaning requirements of the dirt. According to the cleaning object and cleaning requirements, taking into account the cleaning cost and feasibility, choose a formula that can meet the cleaning requirements to clean the cleaning object.

solution
Food-grade production lines face various technical obstacles when cleaning,

1. Secondary pollution from general industrial cleaning
2. The cleaning process must meet the requirements of food grade
3. Strict requirements for chemical cleaning
4. Huge costs associated with manual cleaning
5. Some food line cleaning needs to be dried and cleaned without moisture
6. Under numerous technical obstacles, dry ice blasting machine has become the best cleaning choice. At present, in food processing enterprises, dry ice blasting is widely used in dairy industry, beer, beverage, fruit juice, medicinal liquid, mineral water and other food and sanitary industry enterprises. , especially dairy companies. Dry ice blasting is an ideal method for cleaning equipment and pipelines without dismantling the production line. Therefore, there is no need to manually scrub and flush the production line during cleaning, thereby reducing labor intensity, shortening equipment cleaning time, and improving product hygiene quality.

Dry ice cleaning can be automatically integrated and controlled, the cleaning time is short, and the equipment utilization rate is high; there is no need to disassemble the equipment, and the cleaning process can realize semi-automatic or fully automatic control, with high labor efficiency, safety and reliability. Dry ice cleaning has gradually become the preferred cleaning method in various industries due to its fast online cleaning, no damage to precision, and no need for secondary cleaning.

Dry ice blasting technology
Dry ice cleaning technology eliminates many disadvantages caused by traditional cleaning methods. The cleaning efficiency of the equipment is not only doubled, but the cleanliness is also guaranteed. It also makes the cleaning of the equipment more convenient and quick, and completely solves the problem that has plagued food factories for a long time. a problem. Because dry ice is non-conductive, free of moisture, and non-polluting, it is determined that the dry ice blasting machine can be cleaned online without cooling down and disassembling the production line. Dry ice is directly volatilized during the cleaning process, and there is no cost for cleaning secondary pollution. Dry ice online cleaning saves a lot of downtime, improves efficiency, does not need to increase labor and production equipment, and increases output. Longer equipment life, dry ice pellets are non-abrasive. Dry ice blasting does not damage the equipment. In addition, online cleaning avoids accidental damage to equipment during disassembly and assembly. Dry ice blasting has no damage to circuits, control components, and switches. After cleaning, the possibility of equipment rusting is also greatly reduced compared to water cleaning. Therefore, dry ice blasting is widely used in the cleaning of food processing machinery.

Applications of Dry Ice Blasting in Food Processing: The efficiency of dry ice cleaning can be found in many different industries such as food manufacturing and packaging.

Application scenarios of dry ice blasting machine
Bakery Equipment: In the bakery industry, dry ice is used to clean many different kinds of equipment surfaces. Equipment surfaces are often coated with layers of oil, bread crumbs and other baking ingredients. The manual cleaning method is heavy and needs to be disassembled before cleaning. Dry ice blasting has been proven to clean ovens, bread coolers, bag sealers, and shipping equipment without disassembly.
Snack processing equipment: Dry ice blasting is used to clean Ishida scales (radial feeders), areas around conveyors and conveyors, bag making machines and other peripheral packaging equipment on snack processing equipment. Equipment is often coated with oil, grease and seasonings and requires regular cleaning. Dry ice removes contaminants quickly and effectively, reducing downtime and eliminating unnecessary dismantling and start-ups.

Bottling equipment: When dry ice blasting is implemented, bottling equipment can run more efficiently and reduce waste and defective product production. At the same time, the continuous operation time of the equipment is longer. Components cannot be damaged by hazardous cleaning substances. Dry ice blasting can clean labeling machines, glue nozzles, palletizers and other packaging equipment in bottling equipment. Compared with traditional cleaning methods such as sandblasting cleaning, chemical cleaning and hand scraping cleaning, dry ice cleaning has a superior cleaning process. It can perform in-situ cleaning, and can quickly and safely remove glue, dust, residue and other pollutants .
General Equipment Cleaning: Dirt, soot, grease and oil on food manufacturing equipment can cause the machine to malfunction. The use of dry ice blasting reduces many costs in the food production industry and improves the ability of online cleaning of food molds safely and effectively. Internationally, dry ice blasting has been widely used in many food production industries and other related cleaning industries.
Many examples prove that dry ice blasting is a very effective means of hygienic cleaning in food production. Compared with traditional cleaning methods, dry ice cleaning technology can clean all kinds of surface dirt, has minimal environmental pollution, and can not damage the substrate at the same time. At present, this method has become an important supplement and extension of traditional cleaning methods.
